SPECIFICATION forming part of Letters Patent No. 717,988, dated January 6, 1903.

Application iled September 27,1900. Serial No. 31,318. (No modelf) Be it known that we, CUSHINGC. HARLOW and ALEXANDER LINDGREN, both of Brockton= in the county of Plymouth and State of Massachusetts, have invented a new and useful Reciprocating-Brush Machine, of which the following is aspeciiication, reference being had to the accompanying drawings, in which- Figure lis an elevation of the best form` of our machine. Fig. 2 is a sectional view of the moving parts. Fig. 3 is a plan and Fig. 4 an end view of the head of our machine. Fig. 5 shows the brush detached.

Ourinventionis a brush held by clamps in a holder mounted on ways and means to rapidly reciprocate the holder, all combined to form a machine such that the workman can present a boot or shoe to the reciprocating brush, and thereby clean oft the stitches which unite the welt and outsole without danger of injury to the upper. This work has heretofore been done by hand and no' 1nachine-brush adapted to this work has heretofore been known.

In the drawings the frame 'A carries shaft B, with fast and loose pulleys l) b and suitable oil-cups h2 b3, as will be plain from the drawings. Shaft B has a crank-pin b4 at one end, which carries the usual box b5. Our brush-holder is a yoke D with a slotted bar d across the bow of the yoke and two holes through each leg d of the-yoke, through which the guide-rods cl2 extend, and the legs d' of the yoke D also carry clamps cl3, which takeV ears d4 on brush D in order to firmly connect a cylindrical to tit a cylindrical bore in hub F and to hold hub F stationary by means of set-screw f', as this enables hub F and its armsf with rods d2 and the brush-holder and brush to be adjusted to suit the workman, some preferring that the brush shall reciprocate in a horizontal plane, while others prefer a plane more or less inclined to the horizon, and while this feature of our invention is practically of much importance yet it will be obvious that this feature is not dependent upon the other features of ourinvention, for part c may be non-cylindrical and fit a noncylindrical hole through hub F. The ways or rods d2 are preferably short pieces of wire inserted endwise through the holes in legs olI ot' brush-holder D and held -from endwise movement by the heads of screws d5.

The operation is as follows: When the belt is shifted from loose pulley b to fast pulley b, shaft B revolves rapidly, in practice about twelve hundred per minute, and the crankpin b4 and its box b5 in the slot of bar cl cause brush-holder D to reciprocate rapidly on Ways d2, which are held fast in the armsf of hub F, the plane of the ways d2 being adjusted to suit the workman by adjusting hub F on the end of box ct. The workman holds the shoe in his hands and presents the upper edge of the welt to the rapidly-reciprocating brush and cleans the stitches without danger of heating the upper, for our reciprocating brush seems to have no tendency to become with a cylindrical bore on the cylindrical end brush-Carrier on those Ways; and means to cause the revolution of the crank-shaft to l'eciprocate the carrier.

3. In Combination a crank-shaft; a hub a carriage on these Ways; and means to cause 1o the revolution of the shaft to reciprocate the carriage.
